Only the crust. The temperature and pressure increases as you go further down into the earth.
how scientist were able to arrive to the district layer of the earth
Scientists have been able to determine the composition of earth's layers using various ways. In most cases, samples have been taken and studied so as to determine the layers of the earth.
Severals methods are all combined to give the scientist info on the layers of the Earth. For example they study the influence of the earth on orbits of the moon and other planets (mass distribution of the earth, mass density). They study the way seismic waves go through the earth which gives knowledge of layers. They use wave to sound. They examine sample of earth.
- By using seismic waves .
making inferences based on data from seismic waves.
which layers of the earth have scientists been able to explore
because they haven't quite gotten that far in technology to create a machine to go to the flaming hot center of the earth

The crust. We have not been able to access the other layers.
The outer layers can be seen directly; the inner layers can't, to a great extent (though neutrinos from the nuclear reactions get out immediately, and can be observed). Much of what happens inside the Sun is deduction, from what is known about how matter behaves.

Sunspots, prominences and flares are all manifestations of magnetic fields, and these are indicators of processes going on deeper within the Sun. Also, just as earthquakes can help geologists study the Earth's interior, so can "sun-quakes" provide info about the Sun's interior.
Looking at the whole earth is is layered with the densest materials in the core and the lightest materials forming the surface. This is because it was once molten and was therefore able to differentiate into density stratified layers. Looking in finer detail at the surface of the planet, the process of erosion and deposition of rocks causes sediments to be laid down in layers parallel to the surface of the planet. These then get deformed when the continents move and the layers can be seen in outcrop.
